Legal Question in Civil Litigation in Colorado

Re: civil law

If your ex left his stuff behind when he permanently moved out, you have no duty to store it for him, and can even charge reasonable storage fees if you do.

Write him a letter, tell him he has 30 days to collect whatever is his that he wants (make sure you're not alone if and when he collects it), and that if he doesn't then you'll sell it or junk it. Any money you make on his abandoned property is yours.
